1. A method for treating a wound comprising the steps of:
- providing a transducer having a distal radiation surface arranged a distance from the surface of the wound for emitting ultrasonic energy and defining at least two orifices therethrough;
introducing a liquid to the distal radiation surface via a first of the at least two orifices;
introducing a gas to the distal radiation surface via a second of the at least two orifices, wherein the liquid and gas form a gas-liquid spray; and
delivering the emitted ultrasonic energy to the wound through the gas-liquid spray, wherein the ultrasonic energy penetrates the wound tissue to a beneficial depth to provide a bactericidal and a therapeutic effect for decreasing the healing time for the wound.

Abstract
The method and device of the present invention for ultrasound wound treatment includes a transducer to produce ultrasonic waves. The ultrasonic transducer has tip with the distal end (radiation surface). A liquid is directed to the radiation surface throug central orifice or separate tube wherein an directed atomized particle spray of the liquid is created upon contact of the liquid with the radiation surface. The spray directed to the wound from at least 0.1 inches transmits ultrasound waves trough particles and has an irrigation, mechanical cleansing, liquid energizing and bactericide effect.

13. An ultrasonic treatment system comprising:
-
a transducer having a distal radiation surface and defining an orifice therethrough; and
a fluid source in fluid communication with the orifice; and
an ultrasound generator for activating the transducer for generating ultrasonic energy therefrom, wherein, during treatment of a wound, fluid introduced to the distal radiation surface via the orifice is formed into a spray, wherein the fluid includes one of a liquid and a gas, wherein the generated ultrasonic energy is delivered to the wound through the spray, and wherein the ultrasonic energy penetrates the wound tissue to a beneficial depth to provide a bactericidal and a therapeutic effect for decreasing the healing time for the wound. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)

21. A method for treating a wound comprising the steps of:
-
generating ultrasonic energy at a distance from the surface of the wound, such that the generated ultrasonic energy propagates through a gaseous medium;
introducing a fluid in at least one propagation path of the generated ultrasonic energy to produce a spray, wherein the fluid includes a liquid and a gas which are introduced via at least one orifice aligned with the at least one propagation path; and
delivering the generated ultrasonic energy to the wound through the spray, wherein the ultrasonic energy penetrates the wound tissue to a beneficial depth to provide a bactericidal and a therapeutic effect for decreasing the healing time for the wound. - View Dependent Claims (22)
